Research and improvement of DSR protocol in Ad hoc network

DSR protocol is one of the representatives of Ad hoc network with on-demand routing protocols, whose working process is mainly divided into two parts: detect and maintain routings, wormhole attack is a special way to attack routing protocols of Ad hoc network. According to the analysis of DSR protocol and conditions of wormhole attack, the process and algorithm of wormhole attack to DSR protocols have been researched. Eventually, ways are presented to improve DSR protocols. © 2010 IEEE.
